Call of Duty Modern Warfare 3 is finally out! Though the release date was today, it was sold early at some places by accident like Kmart and stolen in mass quantities in places like France.

Those lucky people got to play it ahead of time. Whether you preordered it, downloaded it from the Steam client, etc — you’ll be satisfied when playing it after a couple rounds of slaying your friends in multiplayer!

It is available on Windows XP / Vista / Windows 7 PCs, Xbox 360, and PlayStation 3 (PS3) consoles. It’s even available on the Nintendo Wii and DS handheld.

Though our guide is lacking right now, we will update this as we learn more game fixes for Call of Duty Modern Warfare 3 crashes, freezes, controller issues, failures to launch / black screen, etc.

If you know any solutions for game problems that we don’t, please let us know! This first person shooter (FPS) deserves to be played perfectly.

Call of Duty MW3 Matchmaking Does Not Work

Can’t join any matches? No worries — you are not alone. The servers are being swamped right now since the game was just released. The servers are simply overloaded. This will begin to die down as the game loses its initial buzz. Be patient until then or try again a bit later (joining during off hours has an increased rate of success).

CLAN TAG DENIED DUE TO PROHIBITED TEXT

This error message has been occurring for people who reach level 7 and unlock the Clan Tag capability in the Call Sign Menu. For whatever reason, people cannot enter a lot of different tags. This isn’t happening to everyone, but it is currently unknown as to why you it is happening to only some. While I recommend being careful with your word choice since certain words are denied automatically, it may deny even words or gibberish text that is fine. This will likely be fixed soon though so be patient. It may even be related to the servers being swamped again.

Elite Founder Status / Subscription Code No Longer Available / Invalid

Do NOT contact the Activision / Infinity Ward / Sledgehammer Games / Treyarch teams. Wait a couple of days and try again. Do not wait until the 13th though if you have the Hardened Edition, as it does expire.

Double EXP / XP Points From Mountain Dew

Have Mountain Dew or Game Fuel? You are promised extra points — double in fact — once it is applied to your XBL gamertag. After following the instructions on the case of Mountain Dew you may notice that you are NOT getting double the amount of experience! BOOO! People have reported calling the hotline and having their informaton taken down so that they can be given the points, but as of right now I have not confirmed if this works. Regardless, be sure to enter your code on the rankedup website.

Graphics Textures Messed Up

Do your textures look like they are low quality, ugly, glitched, fuzzy, etc? There’s a fix for that. Under ADVANCED options select “NATIVE” for image quality. A patch will come out eventually to help solve the actual problem, but this works until then.

Can’t Get Online

If you cannot get online, then try the following.

— Disable your firewall
— Delete/rename ClientRegistry.blob and then restart your Steam client
— Enabled the “dedicated server” option
— Ensure your router is allowing the game to connect (putting it in game mode helps)

Apparently there are many problems with Orange Broadband and Netgear routers. If this is the case for you then update to the NEWEST FIRMWARE! Also, for Netgear (these directions are for DGN1000 model in particular, but easily can be applied to other routers) go to your ADSL settings area and set the multiplexing method so that it’s LLC-BASED. Also be sure to set the DSL Mode to ADSL2+. Thanks Chris Hewitt for posting the link!

Call of Duy Modern Warfare 3 Daily Challenges Not Working

CoD MW3 has been failing to acknowledge when people have done the daily challenge. Kill counts sometimes aren’t recognized, etc. This may be related to the servers being swamped too.

For Mission GOALPOST – “Error Reliable Command Buffer Overflow”

This error is going to be solved soon enough so no worries. You can still beat it though by following the person or to jump in the building that has a broken window (located on the right). If you follow the street, that is when the error is triggered, so avoid it.

Call of Duty Modern Warfare 3 Sound Not Working

Is your music / sound / audio messed up for Cod MW3? No problem. The following solutions usually will fix it!

— Those using a multi-speaker setup that is 7.1 or even 5.1 may have success if setting it to 5.1 (if you have a 7.1 configuration) or even to a 2.1
— Lower your Hardware Sound Acceleration and/or Sample Rate Conversion Quality through Start -> Run -> DXDIAG -> DirectX Features (you can also do this in the Control Panel -> Sounds & Audio Devices -> Speaker Settings -> Advanced -> Performance

CoD MW3 Game Ports

Here is the port information for those who must enable ports on their routers, firewalls, etc. or have to forward them. This is good to know if you have the NAT type as strict.
TCP: 3074 and 27014 – 27050
UDP: 3074 and 27000 – 27030

This game fixes guide needs a lot of work still. Please submit any information you may have! Also, feel free to complain about the Lag / Latency Compensation that was implemented in this game…that helps slower internet connections slaughter people with faster internet connections 🙂
